nnenn'rrc snrnns'ron.
Specification of Letters Patent.
Application filed December 13, 1906. Serial No. 347,597.
To all whom 112? may concern:
Be it known that I, Gnone ULLmon, a citizen of the Commonwealth'of Australia, residin at Broken Hill, in the State of New South, vales and said Commonwealth, have invented new and useful Improvements in Magnetic Separators, of which the following is a specification.
This invention relates to the magnetic separation of paramagnetic ore, or 0 'sub stances of different degreesof positive mag netic susceptibility.
It has been devised for the purpose of providing a simple and highly efficient machine capable of producing ore concentrates of the highest grade.
One of the main features of this invention is that it provides, in a single mechanical construction a magnetic separator possessing zones of dificrent magnetic strength in a single magnetic field so that the ore particlcs, whether of the strongest or weakest magnetic susceptibility will be strongly attracted and held against the surface of certain separating rings, hereinafter described, while passing out of the magnetic field.
In order that the invention may be readily' underst 0d, it will be described by reference to the ccornpanyingdrawings in which Figure 1 1s a s1de elevation partly 1n section of a magnetic separator constructed according to this invention, while Fig. 2 is a plan thereof partly in section. Fig. 3 is a diagrammatic plan showing the construction of a separating disk or ring used in the sepa rater, scribed. Fig. 4 is a section through said ring, also showing a pole piece of one of the electro-magnets and a conveyer belt forming part: of the machine. Figs. 5 and '5 are diagrammatic views, illustrating the application of an armature in the magnetic field for the purpose of drlvmg the moving parts of the separator, as hereinafter described.
The magnetic ore separator'disclosed in Figs. 1 and 2 comprises,a plurality of radial magnets 1, four being shown as a convenientnumber for purposes of illustration, any convenient number being used in practice and each being provided with a segmental pole piece 2, the whole being supported upon astandard 2 Above these magnets 1 are arranged one or more vert-i cally adjustable separating rings mounted upon a shaft 4 and arranged to rotate in a and hereinafter particularly .de-
. ring 3.
horizontal plane a short distance above the segmental pole pieces 2. The separating rings may be driven in any suitable manner as shown in Fig. 1 by means of an electric motor 8 having driving connection with a worm and gear 9. If preferred, an arms ture 9*, see Figs. 5 and 5 such as is used in Patented Sept. a, rare.
a dynamo-machine may be placed between the inner poles of the magnets 2 of the separating magnets and be secured upon the shaft 4 of the separating ring 3, thus eliminating any separate driving motor for transmitting motion to the said rings.
The material to be treated is fed into the magnetic field from a feed hopper or hoppers 5 or other suitable device, by means of a conveyer belt or belts 6 or other suitable feeding devices, in even regular quantities and in an evenly divided or comminuted state As the ore passes through the mag netic field, formed-by a pole piece 2 and the rotating separating ring or rings 3, the magnetic particles are attracted and held against the said rings 3 until they are can ried over the edge of the belt 6 out of the in iluence of the magnetic field, when they fall into suitably disposed receptacles. The nonmagnetic ore is discharged by the belt 6 into another receptacle.
The separating ring as shown in. Fl 1 may have its gathering face or surface wedged-shaped in cross section, or as shown in Figs. 3 and 4 the attracting surface of said ring may be flat and the ring itself provided with a circular series of small i or soft iron or other suitable material and in actual construction may consist of short pieces of pipe or tubing which are suitably secured to and carried by the separating By using these short pieces of tubing or pipes 3 in conjunction with the separating ring 3. the lines of force passing through the pole pieces substantially upon parallel lines will he suddenly and strongly condensed and concentrically converged from the surface of the pole pieces 2 toward the edge of the tubes or pipes 3. This concentric concentration of the lines of force may be varied by making the ends of the tubes or pipes 3 square, pointed or wedge-shape at their free ends. 'With'this constructiomgreat disturbances of the lines of force are produced in the field of mag-.
netic force and separating action relative to the metalliferous particles is thereby com siderahly increased.
That is claimed 'is:-
1. In a magnetic separator, the combina-,
tion with a magnet, of a member of magnetic material 'revolubly mounted over the pole piece of the magnet and magnetized by induction from the latter, a conveyer moving between the pole piece and member, said pole piece extending across the width of the conveyer.
In a magnetic separator, the combination of radially supported magnets having segmental pole pieces, of a rotating ring, of magnetic material over the pole pieces and 'magnetized by induction from the latter,
conveyers, each passing between the pole pieces and ring, the segmental pole pieces extending across the width of the conveyers.
3. In a magnetic separator, a series of electro-magnets having pole pieces in combination with a separating ring having a plurality of circularly arranged series of concentric rings for condensing the lines of force within the magnetic field, and conveyer means for passing the .material to be separated between the pole pieces and the separating ring.
4. In a magnetic separator, a separatin continuous ring, a circularly arrange series of concentric rings of magnetic Ina In testimony whereof Ichave hereunto set my hand in presence of two subscribing} witnesses 4 (more ULLRICH.
